Windows only: Open source application Ditto is a clipboard manager that lets you save, manage, and retrieve all of the countless clipboard grabs you make in the course of your day.

Ditto lets you bring up its Quick Paste tool with a handy Ctrl-` shortcut. From there, you can search your clipboards or paste anything contained therein with a stroke of the Enter key, a double-click, or a simple drag-and-drop. Ditto supports all kinds of copies, including files, so literally anything you can copy will find a place in this clipboard manager. You can even keep your clipboard data synced across multiple computers if you need it. Best of all, the Windows-only Ditto is free and open source. — Adam Pash
